Defect Characterization and Segmentation in APS Thermal Barrier Coatings SEM Images Using BES-YOLO11

Automatic defect segmentation of atmospheric plasma sprayed (APS) thermal barrier coatings (TBCs) from scanning electron microscopy (SEM) images is essential for quantitative microstructural assessment; however, existing instance segmentation models often exhibit insufficient multi-scale representation and excessive co...
